Undernutrition as a major risk factor for death among older Brazilian adults in the community-dwelling setting: SABE survey.

Objective: To investigate the independent association between undernutrition and death in older adults in a community-dwelling setting.

Methods: This retrospective study was based on the Health, Well-being and Ageing survey conducted in 2000 that included 1170 older adults (≥60 y) from São Paulo, Brazil. Death occurrences were considered through March, 2007.

Effect of a sardine supplement on C-reactive protein in patients receiving hemodialysis.

Objective: The study evaluated the effect of a canned sardine supplement in C-reactive protein (CRP) in patients on hemodialysis (HD) and the compliance and adherence to this supplement.

Design: This was a quasi-experimental study: Participants with a serum CRP of 5 mg/dL or less volunteered to consume a sardine supplement or were maintained on the usual cheese/ham sandwich supplement.

Setting: The study took place in two outpatient dialysis units in Lisbon, Portugal.

Undernutrition risk screening and length of stay of hospitalized elderly.

The purpose was to compare, in elderly hospitalized patients, the performance of widely used nutritional screening and assessment tools and anthropometric parameters with the Nutritional Risk Screening (NRS-2002); and to evaluate their independent association with length of hospital stay. Nutritional-status screening and assessment was carried out using NRS-2002, Mini Nutritional Assessment (MNA), Subjective Global Assessment (SGA), Malnutrition Screening Tool (MST), and anthropometry. Patients classified by NRS-2002 as undernourished had an independent higher risk of longer length-of-stay (> 8 days): Odds ratio = 2.
